The 3rd appearance of Smoke was delayed due to George Locke's entry into the armed forces, and was published by Ella Parker. It included an account of Locke's recent experiences, as well as contributions by Mal Ashworth, John Berry, Sid Birchby, Vince Clarke (Science Fantasy News), and Ken Potter (Brennschluss).

Issue 4 was released in November 1960 and included articles by the editor as well as contributions by John Berry, Lee Jacobs (The Ballard Chronicles), Robert Lichtman, writing on the filming of The Misquite Kid Rides Again), Archie Mercer, Ella Parker, Dick Schultz (later editor of En Garde), plus illustrations by Jim Cawthorn and covers by Arthur Thomson.

Locke also published two issues of Eye Tracks during this time, as well as serving as OE for The International Speculative Publishers Organization, and editor of its official organ, Ipso Facto. Shortly after, Locke left the UK for duty in Africa, where he began publishing a smaller follow up to Smoke, three issues of a fanzine called The Prose of Kilimanjaro, published from 1961 till 1962.

However, in September 1963 the sixth and last issue of Smoke appeared, done for OMPA, before Locke moved on to yet another publication called Deadwood in 1964 and 1965.

Later, George Locke wrote and published fiction under a pseudonym, and in the 2000's privately published a book entitled The Edge of Space.
